SimpleAnimation class

A simple RiveAnimationController that plays back a LinearAnimation defined by an artist. All playback parameters (looping, speed, keyframes) are artist defined in the Rive editor. This takes a declaritive approach of using an animationName as the only requirement for resolving the animation. When the controller is added to an artboard (note that due to widget lifecycles it could get re-initialized on another artboard later) it'll look for the animation. Not finding the animation is a condition this example deals with by simply nulling the AnimationInstance _instance which means it won't be applied during advance cycles. Another approach would be let this throw, but this one is a little more forgiving which can be desireable with files dynamically loaded (downloaded even) at runtime.
